Description

The invention relates to an electrical contact device for an electrical connector and an electrical connector.

Electrical contact devices for an electrical connector are known in various embodiments in the prior art.

Out EP 0 674 358 B1 and DE 18 11 276 A electrical contact devices are known which have a base body and a fastening body, the base body and the fastening body being designed as separate components. The base body and the fastening body are connected to one another in the area of the sides facing each other. The base body has a contact space for accommodating a counter-contact and a contact area for contacting an electrical line.

The object of the invention is to provide an improved electrical contact device for an electrical connector and an improved electrical connector.

The objects of the invention are solved by the independent claims.

An electrical contact device for an electrical connector is provided. For example, the electrical contact device can be used to contact an electrical line of an electrical cable that is arranged in a vehicle, for example. The contact device has a base body and a fastening body, which represent contact elements. The base body and the attachment body are designed as separate components. The base body and the attachment body are arranged next to one another. A side of the base body faces a side of the attachment body in a connection area. In this case, the facing sides of the base body and the fastening body can bear against one another at least at points or over an area. In addition, the facing sides of the base body and the fastening body can be connected to one another at points or over a large area, directly or via a connecting layer. The base body and the fastening body are thus connected to one another in the connection area. The base body has a contact space for receiving a counter-contact. In addition, the base body has a contact area for contacting an electrical line, for example an electrical cable.

The proposed electrical contact device has the advantage that the base body and the fastening body can be produced independently of one another and, in particular, from different materials. In addition, the contact device is easy to manufacture, since the base body and the fastening body are arranged next to one another and are firmly connected to one another. By arranging the base body next to the fastening body, the contact device can be produced easily and quickly. The base body essentially assumes the function of making electrical contact and conducting the electrical connection of the contact device. The fastening body essentially assumes the function of mechanical stability of the contact device and fastening of the base body in a housing. Both the base body and the attachment body can take over the electrical conduction, ie the current conduction. With the proposed two-part structure, with the base body and the fastening body being arranged next to one another, very small electrical contact devices can be provided which have a simple structure and in particular provide high electrical conductivity and enable high mechanical stability. Due to the two-part embodiment, the base body can be produced in an optimized manner with regard to the shape, the production and/or the material to the desired high electrical conductivity and the ability to be assembled with the fastening body. In addition, the fastening body can be produced in an optimized manner with regard to the shape, the production and/or the material to the desired mechanical stability and the ability to be assembled with the base body.
The base body and/or the attachment body have a sleeve shape. The sleeve forms of the fastening body and the base body have at least one outer surface. The outer surfaces of the sleeve shapes of the base body and the attachment body are assigned to one another in a connection area. The outer surfaces of the base body and the fastening body are connected to one another in the connection area at points or over a large area, directly or via a connection layer. In this way, a simple production of the contact device is made possible, with which good stability, a small structural shape and a simple connection of the base body to the fastening body is made possible.

In one embodiment, the fastening body is made of a first material and the base body is made of a second material. The second material of the base body has a higher electrical conductivity than the first material of the fastening body. As a result, a larger proportion of the electrical conduction, i.e. the current conduction, is taken over by the base body.

In one embodiment, the first material of the fastening body has a greater modulus of elasticity than the second material of the base body. In this way, an electrical contact device is provided which has a small structural shape, is easy to manufacture and has a relatively high mechanical stability due to the fastening body.

In a further embodiment, the base body and/or the attachment body are made from a bent and/or a folded plate. By bending and/or folding the plate, the shape of the base body and the fastening body can be produced quickly and inexpensively. In addition, the curved and/or the folded shape of the base body and the fastening body offers increased rigidity compared to the material thickness of the plate. In this way, the mechanical stability of the fastening body and the base body is increased.

The contact space of the base body can have a circular, rectangular or triangular contour in cross section. These forms are particularly suitable for producing the base body using a bent and/or a folded plate made of the second material. In addition, the fastening body can also have a circular, rectangular or triangular contour in cross section.

In a further embodiment, the base body and the fastening body are connected to one another in a form-fitting manner. For example, tabs of the base body or the attachment body can protrude into openings in the attachment body or the base body and realize a form-fitting connection between the base body and the attachment body. The connection between the base body and the fastening body can be realized, for example, using a clinch connection, a caulking connection or a riveted connection.

In a further embodiment, the base body and the fastening body are connected to one another via a connecting layer. The connecting layer can be implemented, for example, as an adhesive layer or as a welding layer. The connection layer is formed between the sides of the base body and the attachment body which are associated with each other. In this way, a compact design is realized with little outlay on materials.

In a further embodiment, the contact device has a spring element which protrudes into the contact space. The spring element is arranged opposite a contact surface of the base body. The spring element is provided for the purpose of pressing the counter-contact in the direction of the contact surface when a counter-contact is pushed into the contact space. In this way, an improved formation of an electrical contact between the mating contact and the contact surface is realized. In particular, the spring element increases the prestressing force with which the mating contact is pressed onto the contact surface.

In one embodiment, the contact spring is designed as part of a side wall of the base body. The contact spring is thus provided with little material expenditure.

In a further embodiment, the contact spring is designed as part of the fastening body, with the contact spring protruding into the contact space. For example, the contact spring can be formed as part of a side wall of the fastening body.

In addition, a contact spring can also be dispensed with in principle. In these embodiments without a contact spring, the electrical contact is achieved by the mating contact resting against the contact surface.

In a further embodiment, the fastening body has a support spring. The support spring is designed to support the contact spring of the base body on an outside. For this purpose, the support spring is arranged opposite the contact space on an outside of the contact spring. The support spring is provided to increase the rigidity of the contact spring of the base body when the spring element is pushed outwards away from the counter surface of the base body when the counter contact is pushed into the contact space. In this way, a contact spring of the base body can be used that has a low mechanical spring stiffness. In this version, the spring rigidity is increased by the supporting spring of the fastening body.

In a further embodiment, the fastening body and/or the base body have a latching element, the latching element being provided in order to secure the contact device in a housing against being pulled out. It is thus possible to arrange the contact device in a housing and to secure it against being pulled out using simple means.

In a further embodiment, a second attachment body is provided, which is connected to the base body. In this way, the mechanical stability of the contact device can be increased without requiring a large attachment body. In addition, through the Providing the second fastening body, the mechanical stability can be increased, for example, against bending of the base body along another side surface of the base body. Depending on the selected embodiment, the second attachment body can be designed identically to the first attachment body. However, the second fastening body can also have a different shape and/or consist of a different material than the first fastening body.

In one embodiment, the base body and/or the attachment body have an elongated shape, with the base body and/or the attachment body being at least twice as long as they are wide or high. The fastening body and the base body are aligned along a longitudinal direction. As a result, a small structural shape is achieved, which enables good electrical contacting of the mating contact with an electrical line connected to the base body.

In one embodiment, the contact section of the base body and/or the attachment body have an elongated sleeve shape. The contact section of the base body and the attachment body can be of the same length. In addition, the contact section of the base body and the fastening body can be arranged at the same height along a longitudinal direction.

In a further embodiment, the base body has crimp tabs in the area of the contact area. In addition, the base body has fastening straps. Furthermore, a cable with an electrical line and with an insulating jacket is provided, with an end piece of the electrical line protruding from the insulating jacket. The end piece of the electrical cable is attached to the base body with the crimp lugs. An end piece of the insulating jacket is attached to the base body with the attachment lugs. This enables a simple and reliable mechanical and electrical attachment of an electrical cable to the base body.

According to the invention, an electrical connector is provided, the connector having a housing, the housing being formed in particular from an electrically insulating material, and the housing having a contact opening, a contact device according to one of the preceding claims being arranged in the contact opening. The contact opening is provided in order to be able to insert a mating contact into the housing and into the contact space of the contact device.
